Abstract:

Based on the whole stand model of Daqingshan, using simulation method, the impact of measurement error of number of trees per hectare, average diameter, dominant height, average height and form height on the whole stand model were studied. The result indicated that, beting estimated by least square method, basal area model, average diameter model, number of trees per hectare model had obvious biases, but dominant height model, average height model and form height model had no clear biases.

Key words: measurement error, whole stand model, least square estimation
